Abstract

A lock with high performance and convenient application is composed of core, blades in core, the structure for preventing drilling and prying, and automatic locking structure of bolt.

Description

Lock

The application system divides an application, and the applying date of original application is 990623, and application number is 99109192.2, and name is called < < lock > >.

The invention belongs to lock, especially performance is high, the blade lock that cost is low, purposes is wide.

The blade lock of prior art has multiple, and GB GB8387-87 is a kind of blade lock that there is no tapered end and lock core.Blade lock of the present invention, is mainly comprised of lock core, tapered end, blade, spring and key.In door lock, also have lock body, dead bolt, driver plate etc.This blade lock is used widely in all kinds of locks, especially take door lock and automotive lock as many.Blade lock pin is generally formed by allumen die casting, is cast lock core.Most automotive lock is this lock core.Also having the stamping forming lock core of a kind of metal sheet, is punching press lock core.Punching press lock core is because structure, technique are simple, lower than cast lock core cost.The blade lock of prior art, ubiquity poor performance, the shortcoming that cost is high.Poor performance mainly refers to not prevent drawing, not anti-drilling, anti-unloading, not preventing universal key.The anti-or not foreign matter of finger of drawing is drawn and is dialled.Have a kind of tool of exchanging work of drawing that master key principle unblanks that uses, on a forked stalloy or steel wire, have can bi-directional movable elasticity hook.This instrument can be opened various blade locks effectively.General blade lock, only needs with two steel wires in fact, one lock core to a layback, give a revolving force, lock core is turned an angle, another root is drawn in spoon groove, make blade gear on the edge of tapered end lock hole, the principle of application master key, can unblank.The anti-outer end structure that unloads finger tapered end is not prevented unloading.

Existing blade lock, also has following not enough:

1, punching press lock core has frame, and this frame has limited vane travels, is unfavorable for improving tooth number and strengthens confidentiality, safety.Existing punching press lock core is joined single head blade, and not only tartar amount is few, and the anti-poor performance of drawing.On lock core, in a hole or lattice, only fill a blade, a blade is joined a spring, and this lock core can not be loaded onto more blade in limited space, in other words, cannot dwindle lock core volume.Cannot improve confidentiality, the scope of application is poor, and cost is relatively higher.

Existing blade, have single head and two first two.Single head refers to an only lock hole that can enter on tapered end of blade.Double end refers to that blade two can enter lock hole.Single head blade is for punching press lock core, and Bipitch bucket is for cast lock core.Single head blade is subject to the restriction of lock core structure, its anti-poor performance of drawing.Bipitch bucket prevents that drawing performance is relatively good.Two kinds of tapered ends all can not be accomplished really burglary insurance effectively, and cost is higher.

2, existing blade insurance measure is few, and weak effect is simple in structure, is unfavorable for improving secrecy.

3, existing blade lock is generally not anti-drilling, though some locks have anti-drilling layer, anti-drilling layer is anti-unloading not.As the anti-drilling layer of prior art can not firmly be connected with tapered end outer casing sleeve, tear the cap rock of tapered end outside, anti-drilling layer just can have been laid down.Lay down anti-drilling layer, tapered end is with regard to non insurance.Have by the riveting of anti-drilling layer on tapered end, though prevent like this unloading, frame mode is not attractive in appearance, cost is high.

4, the key positioner method of prior art and tooth punching method cost are high.There are being on the key location and the anti-ditch muscle of drawing the effect of pulling out.In fact the ditch muscle that lock core matches with key prevents that the effect of drawing is very little, because key need have certain intensity, just must have certain thickness, as long as there is thickness, a spoon groove just has width, has width to enter to draw with regard to difficult anti-foreign matter and dials.Because the comparable key of foreign matter is thinner, shape is more volatile.And these ditch muscle have restricted the global design of lock and have increased processing cost.The tooth punching method of prior art is to go out anodontia key billet, then processes by tooth by required tooth number, and time-consuming like this, cost is higher.In prior art, the key of having opened tooth must be strictly along with tapered end is walked, and the interchangeability of key is poor, is not easy to management.The key of prior art, also cumbersome while assembling blade in lock core, must conscientiously check the number, work efficiency is low.

5, the square tongue of prior art (comprising multidirectional dead bolt), stretches out and retraction, need complete with key rotation lock core or with handle, is inconvenient to like this use.Once forget or old man, child can be with being non insurance.The door lock (uvula is that a kind of head is two-sided pointed, the part of having an effect with dead bolt in lock body) that has a kind of latch bolt band uvula, uvula is subject to the active force of doorframe at closing time, and uvula discharges latch bolt a bit, the part side's of replacement tongue effect.But it is shorter to discharge length, and generally, in 8 millimeters, insufficient strength is good.Moreover, the latch bolt door lock effort of closing the door, because of latch bolt and dead bolt box rubbing surface large, and stroke long due to.When the door lock of prior art is used for inward opening door and outward opening door exchange, latch bolt need be fallen turn over direction, inconvenience is used.CN2100440U discloses a kind of locking mechanism of billiard latch, and its structure is can automatically enter lock-out state after swivel hook dead bolt and the collision of dead bolt box, and object is reliable, laborsaving, and cost is low.Weak point is that applicable surface is narrow, can not be for translation dead bolt, and structure is more complicated.

6, in prior art, rotation strip acts on driving chuck and stirs dead bolt, needs, by a transmission shaft tube, to be commonly called as " navel " and to realize, and this part is made trouble, and cost is high.Driving chuck need be realized and being connected with lock cover by transmission shaft tube.

Chinese patent 93207856-7 discloses a kind of one-way double-rank blade lock core, its structure is that two two unidirectional blades relative in same plane are housed in lock core blade groove, its key is combined by two, forms thus double-row blades, and object is to solve the poor and anti-dial problem of automotive lock confidentiality.Weak point is poor performance, and cost is high.Such as: first this is locked to all blades and press to its wide groove one side, give afterwards revolving force of lock core, then blade is rebounded to narrow groove one side, at this moment, blade has been stuck on the edge of narrow groove, and lock has just been drawn out.Moreover this lock construction more complicated, is difficult to carry out, so cost is also higher.

The object of the invention is to: avoid above-mentioned deficiency, propose various new structures and method, improve the performance of lock, reduce cost of manufacture.About the performance of lock, GB GB8384-87 has stipulated: the content of four aspects such as secrecy, firmness, flexibility ratio, outward appearance.Therefore, object of the present invention is specifically:

1, the comprehensive advantage that punching press lock core cost is low and Bipitch bucket safety is good, propose a kind of Performance and Cost Modeling perfect unity new lock core and with the combination of blade.Increase the quantity of certain volume internal cylinder Leaf, or say, when increasing lock core tartar quantity, dwindle the volume of lock core, improve the lock core scope of application, reduce costs.

2, overcome blade lock not anti-drawing, the not disadvantage of preventing universal key.

3, solve the problem of the not anti-drilling or weak effect of tapered end.

4, provide a kind of simple and easy to do, tooth punching reliably and assembly method.Solution is without the orientation problem of ditch muscle key.

5, make various door locks automatically enter locking states, easy to use.

6, solve to rotate central siphon difficult processing, problem that cost is high.

The object of the present invention is achieved like this:

Door lock of the present invention is mainly comprised of lock core, blade, spring, tapered end, cover cap, anti-drilling layer, key, dead bolt, driver plate etc., is now described below.

One, lock core assembly and assembly method.Lock core assembly refers to the various combining structures that are comprised of lock core, blade, spring etc.

A, change lock core structure.Remove the frame of punching press lock core, the vane hole of lock core or lattice are the tabular without opening shape or the atresia lattice of circumferential perimeter.To increase the stroke of blade, improve tooth number, increase confidentiality and safety, also can, by changing lock core structure, strengthen the intensity of lock core self.

B, punching press lock core assembling Bipitch bucket.Here " the punching press lock core " of indication is all lock cores that formed through punch process by metal material." Bipitch bucket " refers to that blade two can enter all blades of lock hole.The present invention combines punching press lock core and Bipitch bucket.Punching press lock core can be made by a metal sheet, as steel plate, iron plate, copper coin, aluminium sheet etc., in-built Bipitch bucket.Lock core can be axially or doubling warp architecture radially, also can the side of being, circular tube shaped, and as " u " type structure or other similar structures, can there be raised item muscle and/or the breach of minute root piece the inside, and lock core can be the strip of sheet with opening breach.The annex that can have reinforcing rib or gain in strength.Blade is two motion up and down in " u " type groove.Two all can side by side not enter tapered end and play locking action.On blade, can there is the hook of hanging spring---" hanging spring ear ".Leaf spring can be positioned at " u " type groove outside.Lead mutually two blades totally one helical compression spring or adjacent blades totally one elastic supporter.Punching press tapered end is cylindrical, above has the lock hole entering for blade.The tapered end of punching press lock core can be used alone or serves as a contrast in casting tapered end and supports the use.

C, punching press lock core of the present invention also can be used in conjunction with single head blade, and during with single head blade, lock core can not have frame unlike the prior art, is opening breach or strip of sheet.This lock core removes after frame, has increased the stroke of blade, is conducive to increase differential, improves size of key, processes also easier.Change besides the mounting means of prior art Leaf and spring, by spring, hung on the middle support of lock core, change adjacent blades into and mutually support, increase vane travels.Single, double head lobe sheet also can be combined with in same lock core.

D, a hole multi-disc.Be to have two or more blades on lock core one or each vane hole or lattice.Two adjacent blades or a plurality of blade be totally one elastic supporter, and blade can be in the same way or counter motion, and blade is arranged vertically in lock core.As the blade of two relative motions of axially-aligned in a groove or lattice, they share a spring, for preventing that spring from coming off, on blade, can have hook formation, in order to spring, locate.Between blade, can there is partition.Preceding method of the present invention can be in conjunction with application.

Two, blade of the present invention has multiplely, can be following structure:

1, bayonet socket blade, one, blade or two are with one or more breach.This breach may be stuck on tapered end, makes blade cannot adjust to enable possition, thereby prevents foreign matter unlatching.As two of blade and both sides, all can be with a breach, this breach is wider than the specific thicknesses of tapered end.As thick in tapered end 0.8 millimeter, thick 0.5 millimeter of the lock hole edge on tapered end, (this thickness can obtain by the method for punching press or cutting, and this featheredge is conducive to bayonet socket blade and enters), blade breach is wide 1 millimeter.When drawing while dialling person's rotational lock core, breach is stuck on tapered end, thereby cannot be rotated further lock core, cannot unblank.On tapered end, there is the structure snapping in for bayonet socket.Ditch muscle snapping in for bayonet socket as having on die casting tapered end etc. or have stamping parts lining or similar bushing pipe.Bayonet socket blade also can be " T ", " I " type, and projection or the similar structures that is wider than blade left at one, blade or two, and this projection plays the effect of bayonet socket blade.

2, tip blade.One section of being one, blade or two is narrower than middle, and the both sides at two are hypotenuse shape, by narrow, to wide transition, are hypotenuse shape.When illegal rotational lock core certain angle, while making blade be stuck on the edge of tapered end, the blade not blocking is being drawn under the effect of the power of dialling, enter tapered end lock hole, and utilize the extruding force of its hypotenuse that the lock core that has rotated any is squeezed back to latched position, and make jammed other blade be released return, reenter tapered end, lock core cannot be rotated, cannot be successful thereby make to draw group unlatching such as foreign matter such as grade.Because tip blade can be stuck on tapered end lock hole tightly, lock core cannot be turned to draw to pull out required angle, again because tip blade easily automatically resets, thus draw pull out very difficult.As 4 millimeters of one of blade or two head breadths, interlude is wide 6 millimeters, and by narrow, to wide line, blade head both sides are hypotenuse shape.Corresponding therewith, the lock hole on tapered end also can be the hypotenuse groove shape with the first sample of blade.

3, backward vane.It is a lock hole being greater than on lock body of blade.Backward vane does not enter tapered end under lock-out state, does not now play locking action.When foreign matter, draw while dialling, drawn and allocate for firmly, backward vane enters tapered end, plays locking action, stops the behavior of dialling of drawing.Backward vane of the present invention is limited to Bipitch bucket lock core.

4, gathering sill blade, on blade, with a gap slot, this groove is stuck on lock core, plays the guide-localization effect of blade movement.

The use that can respectively or combine of the blade of said structure or lock core, tapered end, or on the present a slice blade of combination.As backward vane is used in conjunction with bayonet socket blade, it is better that it prevents drawing effect.Keyhole on blade of the present invention can be open-type or enclosed type.Be that keyhole has side's opening or astomous poroid.

Three, Anti-drilling lock.Anti-drilling layer is housed in the outer end of tapered end.Anti-drilling layer can be positioned at below tapered end cover cap, can be cup-shaped, sheet, flange shape or analogous shape, porose.In sleeve, with sleeve lining interference fit, be fixedly connected with, also riveted joint, welding etc. is fixedly connected with.Even if now the cover cap of tapered end is torn, also cannot take off anti-drilling headkerchief, cannot destroy tapered end.Also can directly do anti-drilling layer by cover cap, outside sleeve, be fixedly connected with sleeve.Such as making cup-shaped cover cap with the material of 1.5 thick processing, with revolving riveting method, it is firmly connected with sleeve, cry " revolving riveting method "." breach rendezvous method ", sleeve and anti-drilling headkerchief respectively stay corresponding breach, after mutually inserting, rotate in place, and both entangle fastening, fill breach both can not be rotated again, realize firmly and connecting." embedding inlay technique ", sleeve and have the cover cap of anti-drilling function respectively to make corresponding sides embeds his thing and makes it fixing between two corresponding sides.Also the method for available welding realizes anti-drilling layer and is firmly connected with sleeve outside sleeve.Prior art cannot firmly be connected anti-drilling layer with sleeve.Anti-drilling layer self non insurance, whole lock had also just lost efficacy.

Four, a. plain film key and localization method thereof, key of the present invention is plain film shape, without ditch muscle or pellet concave point.Ditch muscle on the key affects the intensity of key.Because having the key of ditch muscle is that maintenance intensity must be thicker.Remove ditch muscle and be conducive to key to do very thinly, key that key is thin also can be thin, is conducive to like this improve the confidentiality of lock and cut down finished cost.

Key positioner method.Lock core inside and outside two ends all has location-plate or similar structure.2 fixed lines, key is located.As there is a location-plate entrance of lock core outer end, can be held concurrently by keyhole before anti-drilling board or lock core, the root of key can be blocked.There is a location-plate lock core inner end, can be held concurrently by correlated parts, and key tip is blocked, and key has just been located in lock core like this.Also can there be location-plate the centre of lock core, and also available " blade positioning mode ", has the blade playing the role of positioning in lock core, and key is blocked to location in opposite directions.

B, key teeth notching method.During key base, go out together unified basic profile of tooth, and then open an above tooth, as open 1-2 tooth, be the special tooth profile key with personal characteristics.According to the rule of tartar permutation and combination, its adjacent encoder differs a tooth.Adjacent code as 12345 can be 12344.Be reflected in the tooth differing on the key.During tooth punching, the most shallow tooth can fix on more than 1 millimeter, to guarantee the difference with basic tooth." basic profile of tooth " is the unified tartar spread geometry on key billet that is reflected in of a kind of tooth punching of setting according to the functional requirement of each side.Basic profile of tooth can have multiple difformity.Output basic tooth and can lose the total quantity that tartar is arranged, but key tooth flower amount of the present invention can reach more than ten million kind, losing some does not affect its security performance.This key is also very easy to assembling, such as completely first filling the blade of basic profile of tooth, then fetches arbitrarily a set of key one of having opened specific tooth and inserts, and can find not to be inconsistent the blade of profile of tooth, then this blade is changed, and assembles the merit of accomplishing.And do not need to resemble prior art key in process of production, can not leave lock, otherwise just fall apart, be hard to tell the lock that key is corresponding.

Five, the method for work of dead bolt.Be the square tongue of door lock automatically entering locking states by various triggering controlling organizations at closing time, do not need to transmit with key.The square tongue here can be circle tongue or turn tongue or multidirectional dead bolt.From the motion mode of square tongue, two kinds of minute translation and rotations, the translation side of being tongue

be moved into locking states, turn the tongue rotation of the tongue side of being and enter locking states.

1, square tongue escapement." catch ", refer to square tongue to keep a grip on, control and do not allow it enter dead bolt box, in opening; " indulge ", refer to decontrol, allow it enter dead bolt box in locking states.Side's tongue is sharp, can resemble latch bolt sample, and one side point, also can two-sided point.Side's tongue only part is with inclined-plane.As pointed in being inclined-plane on a bicylindrical dead bolt socket cap.During opening, tip is exposed at outer 8 millimeter of lock body, and this is because door and doorframe are gapped, add top tongue complete de-catch to move need stroke, therefore expose generally, in 8 millimeter, be advisable.

The escapement that has dead bolt in lock box, its escapement can be a fork, or elasticity bolt, fork can be with a spring, recipient's tonguing goes out the acting in conjunction power of lock box action and spring, fork is in respectively diverse location, can controlling party tongue in unlatching or closed condition.On side's tongue, there is the structure of accepting and driving fork action.After opening the door, the escapement structure side's of blocking tongue automatically, only stretches out 8 millimeter.At closing time, the side's of release tongue all enters dead bolt box automatically.Its penetration depth can as 10 millimeters, add 8 millimeters, inclined-plane more than 6 millimeters, and square tongue length can be in 18 millimeter.

2, uvula escapement.On the limit of square tongue, there is a uvula, uvula is made by metal sheet roof covering, and uvula head is two-sided point or one side point or circular-arc, and uvula self or by the auxiliary side of acting on tongue is controlled at square tongue to open or locked position.On side's tongue, there is the structure of accepting little tonguing.During opening, uvula is exposed at lock body outside 8 millimeter.While opening the door, uvula can automatically block dead bolt and not expose.At closing time, uvula is subject to doorframe active force, the side's of acting on tongue, and the side's of release tongue all enters dead bolt box automatically.Its stroke is more than 6 millimeters.Uvula has numerous species, has straight chip, circular pipe type, clubfoot formula; Single type, multi-piece type.Straight chip is that uvula is straight sheet; Circular pipe type refers to that uvula is circular tube shaped; Clubfoot formula refers to that uvula pin is crooked; Single type refer to uvula only one can finish the work; Multi-piece type refers to that uvula need be equipped with auxiliary and complete escapement work.

3, latch bolt escapement.The latch bolt of prior art has uvula effect concurrently, plays the escapement effect of the other side's tongue.During opening, latch bolt is exposed outer 8 millimeter of lock body.In lock body, have escapement in latch bolt, its escapement can be on oblique tongue rod, to be equipped with a shifting block, and shifting block can be a sheet metal, above has the structure that drives fork motion, acts on fork, and the fork side of acting on tongue is controlled at square tongue to open or locked position.On side's tongue, there is the structure of accepting escapement action.

4, discharge multidirectional dead bolt voluntary insurance, above-mentioned dead bolt automatic blocking structure can be used in multidirectional locking, and discharges multidirectional dead bolt simultaneously and automatically enters safety position simultaneously.As the top of release simultaneously, the three direction tongue on door limit, below door.

Six, two-in-one driving chuck.Remove the transmission shaft tube of prior art, on driver plate, process a pair of flange and come, with this, flange is replaced to transmission shaft tube, realize being flexibly connected of driving chuck and lock cover, in hole on the cover board, move.Can there be two kinds of modes: a kind of in-flanges, middle to turning up from driver plate, the aperture of inserting transmission bar on driver plate can be equally large or larger with the aperture on cover plate, on driver plate, to reserve the movable desired position of transmission bar, now the width of transmission bar is decided by the size of cover board hole and driver plate flange, can be more smaller than cover board hole, and little 0.5 millimeter, larger than the width between driver plate flange both sides, to cover board hole or driver plate hole, can hold and can rotate degree freely greatly.Also can not be like this, no matter how structure changes, the transmission bar of in-flanges structure, and its width must be the width that is greater than the distance between driver plate in-flanges both sides, or in driver plate hole, has the structure of accepting the action of transmission bar.Another kind is flanging, from driver plate outside to turning in, dig equally two flange come (certainly, no matter in-flanges, flanging, can be to dig two above flange to come, but with two for well.) with this, flange is replaced to transmission shaft tube.Now the width of transmission bar can need to decide according to the size of transmission bar and action, also can with in-flanges one spline structure, or other suitable construction.

Compared with prior art, tool has the following advantages in the present invention: 1, remove the punching press lock core of frame, increased the stroke of blade, be conducive to improve tooth number.Support the use Bipitch bucket, increase the anti-ability of dialling of drawing of tapered end, both improved performance, reduce costs again.2, variously anti-draw blade, improved widely anti-the drawing of blade lock and dialled performance.3, a hole multi-disc can be dwindled lock core volume, increases the scope of application, can improve tooth number again.4, sleeve is firmly connected with anti-drilling layer, has strengthened the protective capacities of lockset self.Various methods of attachment are not only easy but also more reliable than originally.5, new key positioner method is simpler than original technology, and handling ease, has reduced cost.6, tooth punching method is simpler than former technical matters, and percent defective is low, is particularly conducive to and exchanges and assembling.7, prior art can only make to turn tongue and is automatically locked in position, and the present invention can make all dead bolts be automatically locked in position, and structure is simpler.8, use driving chuck of the present invention than former technology few complex parts, and performance is in the same old way reliable, has saved product cost.
